Description
Technical field
The utility model is related to a kind of spring pull-down unit.
Background technology
Existing pull-down unit is generally free pull-down unit, bears a heavy burden for polylith heavy burden piece, makes the overall weight of whole apparatus too
Greatly, not only cost is high, carries also highly inconvenient.
The content of the invention
For above-mentioned problem, the utility model is provided a kind of spring pull-down unit, is kept down being pulled through using guide rail
The stability that spring is moved towards in journey, replaces usual heavy burden piece using the elastic force of spring, significantly reduces the weight of integral device,
Reduce cost.
To achieve these goals, the technical scheme of the utility model offer is：A kind of spring pull-down unit, its feature exists
In it includes stablizing bottom plate, frame, heavy burden spring assembly, guide rod, pulley one, pulley two, bracing wire, pull bar, mat and seat
Pad；
Described stable bottom plate has three pieces, is respectively welded at the bottom of frame, the stability to keep whole apparatus.
The heavy burden spring assembly includes heavy burden ear, upper cross plate, upper hangers, tension spring, lower hangers and lower cross plate；It is negative
There is a circular hole on weight ear, to the connection with bracing wire, heavy burden ear is with upper cross plate by being welded to connect；Upper cross plate passes through with upper hangers
It is welded to connect, lower hangers and lower cross plate are again by being welded to connect；Pass through spring between tension spring and upper hangers and lower hangers
The hook connection at two ends.
Described pulley one, pulley two are by being bolted in frame, the direction for changing power.
Described mat and cushion are foams plastic material, improve the comfort level of user.
Described tension spring is extension spring spring hook and is many, and the user of different stage is using varying in weight, more with bullet
Spring realizes the regulation of different weight.
Japanning after the equal sanding and polishing in all welding positions.
Compared with existing structure type, the utility model instead of traditional heavy burden piece with spring, move the bullet of spring
Power replaces bearing a heavy burden, and significantly reduces the weight of integral device, and effectively reduce cost.
Brief description of the drawings
The spring pull-down unit schematic diagram that Fig. 1 provides for the utility model embodiment；
In figure：1st, stable bottom plate, 2, frame, 3, heavy burden spring assembly, 4, guide rod, 5, pulley one, 6, pulley two, 7, draw
Line, 8, pull bar, 9, mat, 10, cushion.
The heavy burden spring assembly schematic diagram that Fig. 2 provides for the utility model embodiment；
In figure：3.1 heavy burden ears, 3.2, upper cross plate.3.3rd, upper hangers, 3.4, tension spring, 3.5, lower hangers, 3.6, under
Transverse slat.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, being a kind of spring pull-down unit structural representation that the utility model embodiment is provided, it includes steady
Determine bottom plate 1, frame 2, heavy burden spring assembly 3, guide rod 4 with, pulley 1, pulley 26, bracing wire 7, pull bar 8, mat 9 and cushion
10；Heavy burden spring assembly 3 instead of traditional heavy burden piece, and the elastic force of spring replaces the gravity of heavy burden piece, significantly reduces entirety
The weight of equipment, and the probability of the casualty accident effectively in reduction unloading process.
Referring to Fig. 2, be the utility model embodiment provide heavy burden spring assembly schematic diagram, including heavy burden ear 3.1, on
Transverse slat 3.2, upper hangers 3.3, tension spring 3.4, lower hangers 3.5 and lower cross plate 3.6；There is a circular hole on heavy burden ear 3.1, be used to
With the connection of bracing wire, heavy burden ear 3.1 is with upper cross plate 3.2 by being welded to connect；Upper cross plate 3.2 passes through the company of welding with upper hangers 3.3
Connect, lower hangers 3.5 and lower cross plate 3.6 are again by being welded to connect；Between tension spring 3.4 and upper hangers 3.3 and lower hangers 3.5
Connected by the hook of both ends of the spring.
The utility model is a kind of spring pull-down unit, and traditional heavy burden piece is instead of with spring, moves the elastic force of spring
Instead of bearing a heavy burden, the weight of integral device is significantly reduced, and effectively reduce cost.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Described above, preferred embodiment only of the present utility model is every according to this not to limit the utility model
Any trickle amendment, equivalent substitution and improvement that the technical spirit of utility model is made to above example, should be included in this
Within the protection domain of utility model technical scheme.
